Is it possible to update Android to 5.0. We update Android over the air. How to update Android using ADB and Fastboot

Today, many of us actively use tablets with the Android operating system (OS), which needs to be updated periodically. How to do it? There are several ways, which we will discuss below.

Of course, it is wrong to say that updating the OS on a tablet is a mandatory procedure. However, we still recommend that all users do this. Why? There are several reasons for this:

Without updating the firmware, you will not be able to use all the capabilities of the device.
The tablet may even stop functioning normally.
Each update fixes various errors, improves the functionality and interface, which means that using the device becomes easier and more convenient.
Without an updated OS version, it may be difficult to install new programs or games.
Changing the firmware also improves the system for protecting confidential information contained in the device’s memory.
The new version of Android improves the performance of the tablet, that is, web pages load faster (though not much), the work of some programs speeds up, the number of freezes decreases, etc.

Finally, it should be noted that updating the OS removes a lot of unnecessary information and data. This frees up a significant amount of RAM and hard drive space.

There are several ways to update Android on your tablet. First of all, let's talk about automatic update . Moreover, this is the most common option for changing the firmware.

As a rule, when a new version of Android OS is released, a notification appears on the tablet screen. Most often, it looks like a pop-up window in which, in addition to information about the possibility of changing the firmware, a request for permission to update the system is displayed. In this case, click “yes”, “allow”, “update”, etc.

As a result, the latest available firmware version is downloaded directly to the tablet and installed automatically. The maximum that is required of you is to agree several times with what will appear on the display.

However, remember that for automatic operation on a tablet you need a reliableWI— FI-Internet connection. It’s just that the size of the installation package of the new firmware sometimes exceeds 500 MB. It is quite difficult to download such a large file via a 3g or 4g connection. In addition, make sure that the battery charge is at least 40%. After all, if the tablet turns off during an update, this is fraught with serious consequences.

On average, it takes from 5 to 20 minutes to update the Android OS to the latest version (to 6 or 7 depending on the gadget itself). However, before starting the update procedure, it is recommended to close all applications. Don't be alarmed if your tablet turns off and on again several times. This is done in order not only to correctly install the new firmware, but also to optimize the applications available in the device’s memory. Otherwise, they may stop working correctly with installed updates.

How can I check if an updated OS version is available for my tablet?

To do this, you need to go to the “Settings” section. Next, scroll the list almost all the way down. There should be an item called “About the tablet” or “About the device”. Enter it. In addition to various information about the model itself, you will also find an indication of the current version of Android. There will also be a “System Update” button. If it is active, then after clicking on it, the download of the new firmware will begin. If you have the latest version of Android installed, then nothing will happen.

How to update Android via computer? It's not that complicated. You will need to connect the tablet via a cable to your PC or laptop. Then you will need special software. For example, the Kies application from Samsung (each vendor has its own similar software: Lenovo has Downloader Lenovo, Huawei has HiSuite, LG has PC Suite, etc.).

This utility will check whether the latest firmware version is available on the manufacturer’s servers. The result will be sent to the user in the form of a corresponding window. If an update is available, an Update button will appear. Click it, read the user agreement and study all the necessary information. Where necessary, do not forget to check the box next to the items “agree”, “allow”, etc.

We must not forget about another way to update the Android version. For this all you need is:

Go to the website of your tablet manufacturer - Huawei, Asus, Explay, Acer, Irbis, etc.
Then find the appropriate section where you can download the new version of the OS. As a rule, you need to first click on the “Support” link, and then find the “Downloads”, “Updates” or something similar there.
Next, select the firmware for your specific tablet model.
Download the special file and open it.
Follow all installer instructions during the installation process to change the OS to a new version.

A special utility will also help you update the Android version on your tablet. It's called "AnyCut". Using this program is easy. Moreover, with the help of this utility, the system update process is simplified as much as possible. Let's tell you in more detail:

First you need to download “AnyCut” to your device. For example, through the Play Market.
Next you will need to install the program.
Then open the utility and activate the “System Information” item.
Click on “Check for updates”.
The program will check if there are new firmwares. If yes, it will offer to install them.

The advantage of AnyCut is its simple and understandable interface (even for a beginner). At the same time, you can check for updates through this utility in a few seconds.

Possible consequences after updating Android OS on the tablet

Many people are interested in the question of what problems with the device may arise after updating the Android OS. In fact, if you do everything correctly, then there will be no problems. At most, some applications will disappear or programs that are incompatible with the updated version of the OS will not work.

New icons may also appear on the desktop. These are the programs and applications that are provided by the developers. Typically they cannot be removed. However, many of them are absolutely unnecessary, and many do not even use them. You just have to put up with the presence of such applications and programs in the tablet’s memory.

In addition, updating the OS is not always useful for those devices that were purchased a relatively long time ago (3-4 years or more). The fact is that progress does not stand still, and new firmware is tailored for powerful and modern devices. As a result, the latest version of Android OS can even harm an old tablet.

Is it possible to return the old firmware version?

It's quite difficult. After all, on many devices there is no official option to “roll back” to the previous version. Of course, some craftsmen suggest downloading from the Internet and using various programs that return most of the functions and capabilities that were relevant with the old firmware. But all this is unoriginal software, often harmful to the entire system.

Therefore, it is best to take a closer look at the new version of Android and use it for at least a few days. Most likely, you will get used to the different interface and appreciate the new features. After which the desire to “return it the way it was” will disappear.

If, after a couple of days, you are still not used to updating the OS, then you can return the basic factory firmware. That is, the one that was installed on the tablet when it was purchased. To do this, you need to go to settings and find the “Reset settings” item. Mostly it is located in the “Confidentiality” or “Restore and Reset” sections.

On a note!

It is extremely important to note that tablets from different manufacturers have certain features for updating the Android OS. For example, for Samsung devices, to change the firmware to a newer one, you need a “Samsung Account”. Not to be confused with a Google account. You can create a Samsung account in the “Settings” menu by selecting “Accounts and synchronization”. Here the user will have to go through different stages of registration, specify a mailbox, and come up with a login and password.

Android is an operating system that has many versions. A user who keeps up with the times undoubtedly wants to try new versions. To do this, you can buy a gadget with the latest version already installed or upgrade Android to that. But not everyone knows how to update Android. We will tell you how to install a new version of Android in this article.

We offer step-by-step and detailed instructions for updating Android. In order to understand how to update Android on your device, you need an Internet connection (preferably Wi-Fi, so as not to empty your mobile account).

Android updates are individual for each smartphone or tablet. Therefore, there is no universal software or program for PC to “update Android”. The update method common to all device models is updating the Android version over the air.

How to improve the version of Android on your phone

Perform a series of simple manipulations:

go to " Settings» system of your Android device and connect to the Internet using Wi-Fi
if you have a new Google account, go back to " Settings" and go to the section " About the smartphone (tablet)»

Allow automatic updating of the operating system. When a new firmware version is released, you will see a corresponding message on the tablet

click " Restart and Install" This way you will run the update and within half an hour your device will be updated to the latest version of Android

The Android update process is individual for each individual brand and device model

Android update. What are the risks of Android OS updates for a phone or tablet?
Like any operating system, Android is improved, improved, made more productive, and individual parts and operating principles are optimized. It is these fixes and improvements that include official Android updates, which from time to time appear on the screen of your Android mobile phone or tablet in the form of a notification.

It should be noted that you can manually check for updates for your device, be it a phone or a tablet. This is done in Settings, point About the Device where click Software Update. After this, the device update settings will open in front of you. Click the button Update to check the new version of android for your device.

Android update

As it was already written about the update for the Android operating system, this is a very good and correct thing, you should not be skeptical about it. Android updates are designed to improve the performance of your device and make it more convenient for you.

There are big updates and micro updates. Large updates usually require more traffic to download the update itself from the Internet. On average, a large update requires about 500 MB of information downloaded from the Internet. Micro updates tend to be smaller in size, averaging 70 MB. In any case, it is recommended to use Wi-Fi for updating, with a good Internet access point. Let's take a closer look at these two types of Android updates.

Major updates usually affect the entire device and are aimed at global changes. Major updates entail a minor change in the Android OS version, which you can view in Settings, in point About the device, when you open it you will find in the column Android version, information about the current version of your OS. Such large-scale updates can slightly change the appearance of the operating system, making it a little more concise.

Micro updates are minor patches, patches of minor defects and malfunctions that are most often invisible to the eye. In such micro-updates there is no global change of version, but only an improvement and stabilization of the current one.

How does Android update work?

First, the OS prompts you to update, a dialog appears in which you can respond to the prompt to Install a system update or Later, or Install, or cancel the update by closing the dialog.

If you answer Later, then a dialog will appear with a choice of time after which you will be prompted to update again. Usually it is 30 minutes - 2 hours. Below and above this limit there is usually no choice.

When you press Install, Android will notify you that the device will now reboot. For this reason, it is recommended that before installing the update, you must complete all running applications that you have launched, correctly saving all data. After the device reboot notification, your phone or tablet will be turned off.

A few seconds after the device screen goes dark, the Android robot itself will appear, with a geometric figure spinning in the abdomen area; below you will be presented with percentages showing the progress of the device update. Depending on the type of update, this can last from 5 to 20 minutes. After the update progress displayed in percentage reaches 100, the device will turn off and reboot. The first thing that will happen after turning on the device is the optimization of all applications installed on the device so that they work correctly with the installed update. The progress view will show the number of optimized apps relative to the total number of apps. After completing this last update step, and a notification appears that the device has been successfully updated, it is recommended to restart the device manually in order to reduce the number of possible operating errors to a minimum. What errors might there be? It is better to launch applications and services that have been optimized when the OS itself starts, and immediately after the update they were launched with the presets of the old version of Android, and only then optimized, which could cause minor slowdowns in the operation of the device until the first reboot after the update.

What negative consequences can there be after updating Android?

There cannot be any negative consequences as such. After updating your Android phone or tablet, a couple of applications that are not compatible with the new version may be deleted (This happens extremely rarely, and if it does happen, it may only be 1-2 programs that are not updated and for which a better replacement will be found in the Play Store). Also, some desktop icons may disappear (Icons of those programs that are incompatible with the new version).

Along with the updates, several official programs from Google and from the device developer may be installed. This came to negative consequences only because these applications cannot be deleted and you will have them regardless of whether you use them or not.

All these minor inconsistencies are more than compensated for by the new installed Android update, which, as a rule, is better than the previous one and offers more features and makes old features and functions even more convenient.

Is it possible to return to an old version of Android?

Some people, who for some reason were not satisfied with the update of their Android device, are wondering whether it is possible to return the old version of the system that was before the update.

Unfortunately, this feature is not officially supported by all Android devices. It should be noted that craftsmen find a way to manually reflash their phones and tablets to the version they want. Naturally, we strongly do not recommend doing this. This will entail loss of warranty and more. It’s better to think again whether it’s much worse on the updated version than on the old one, we’re sure you’ll like the new version and get used to the changes.

In the event that you have really serious complaints about the new update and you need to somehow fix everything, then: Go to the office. phone developer website (Samsung, Sony, Phillips, etc.). On the website we find the software in the mobile devices section. For example, for the same Samsung phones there is the Samsung KIES program, for other phones there are other programs. Download it, install it and run it. With it, you can install the firmware and do a lot of things. We recommend using this recommendation.

If you have any questions regarding this topic, as always, leave a comment.

The Android operating system is regularly updated to become faster and bug-free. Therefore, every owner of an Android device dreams of having the latest version of this popular operating system on his smartphone or tablet. How to update Android on your phone and what do you need for this? There are a variety of tools available to update your operating system. Let's look at them more and find the most convenient and safe ones.

How to update the Android version on your phone

Android updates appear with enviable regularity. But this does not mean that your device will have the latest version of the operating system. The thing is that manufacturers operate updates, adapting them to their devices.

In addition, if well-known brands devote time to developing new updates, then you won’t get them from little-known ones. As practice shows, devices from Samsung, LG, HTC and some other brands are updated most often.

How to update Android on your phone? In order to make life easier for users, the developers have provided the ability to update over the air (OTA updates). It means that Android devices can download updates via Wi-Fi or mobile Internet.

After downloading new files, they ask for permission to install them. As a result, we get an updated version of the firmware - this is exactly how everything looks on Samsung and on devices from other famous manufacturers.

An analysis of phones from little-known brands has shown that manufacturers do not try to make any updates for the devices they produce - they remain unupdated for years.

How to request an update for Android? There is no need to request anything - Android devices are updated automatically. They independently check for new files and download them, offering installation.

If you suspect that there are updates, but for some reason they are not automatically downloaded, go to “Settings - About device - Software update” and click on the “Update” button - the phone will request updates from the server and download them if available .

Here we will see two more interesting items - “Auto-update” and “Wi-Fi only”. Check the first box if you want to activate automatic checking for updates. Check the second box if you want updates to be downloaded only via Wi-Fi and not affect mobile traffic. Remember that your device will not have the latest version of Android, but the one contained in the updated firmware.

How to update Android on a tablet

To update Android on your tablet, use the method described above. Manufacturers release new updates not only for smartphones, but also for tablets. If your device does not request the update automatically, go to settings and request it manually. Don't forget to check the box for automatic request, if for some reason it was not installed.

Automatic updates for tablets and smartphones are secure for stored data. However, it is recommended to make backups before each update.

How to update Android via computer

Well-known brands release software for their devices that is used to synchronize contacts, share files, and make backups. A typical representative of such software is the Kies program from Samsung. By connecting your smartphone to your computer and launching the program, you can check for updates and install them. The method is quite secure and does not threaten data loss.

How to update the firmware on Android in another way? For this we can use programs such as Odin or Flash Tool (different programs are used for different smartphones and tablets). These programs allow you to download official updates, stock firmware, as well as custom firmware (ported from other phones, modified, etc.). The update process is as follows:

The battery is charged above the 40% level (it is better to charge it to 100%);
The device is connected by cable to a computer or laptop;
Odin (or other suitable software) starts;
The necessary firmware is loaded into the program;
The device is switched to “Download Mode” and the flashing process begins.

After the procedure is completed, the device reboots and runs on the updated firmware.

Please note that the Odin program is used to flash smartphones and tablets from Samsung. To update and flash mobile devices from other manufacturers, you should use the appropriate software and detailed instructions. Don't forget to make a backup copy so you don't lose important data.

How to roll back an Android update

We have already figured out how to update the Android version. But what to do if the new version turns out to be inconvenient to use? Similar inconveniences are caused by some custom firmware taken from other devices.

Resetting to factory settings will not help in this case - the OS version will remain the same. Therefore, rolling back an update is a procedure of re-flashing it to the old version - we get the necessary software, look for the firmware files and try to flash it again.

How to disable updates on Android

If you do not want to receive updates over the air, go to “Settings – About device – Software update” and uncheck automatic updates. Now your device will not check for updates, always working on the current version of the operating system and the current firmware, with all the errors and shortcomings (the essence of updates is to introduce useful corrections).

The market for mobile products is structured in such a way that as new versions of the Android OS are released, smartphone manufacturing companies implement their support in their own, both recently released and already proven models. How it works? When purchasing a new mobile product, the basic version of the system installed by default is available on it. After some period of time, Google releases a new Android release. After six months or a little later, depending on the geographic region, when the new version becomes tested and stable, you can install it on your smart phone. As a result, you get a new, modern interface, support for new applications and more settings and customization. In this material we have compiled a detailed guide for you, how to update Android on your phone.

What is a software update on Android and why is it needed?

You need to be aware that as a result of updating or rolling back the operating system, all data stored on the phone will be irretrievably lost. Be sure to back up all the data you need (address book, notes, photos) to a reliable external storage device before taking any of the steps in this guide. This could be an external drive, a hard drive on a PC (as a last resort, a memory card, but not advisable).

One more nuance. Since updating the operating system will take some time (from 5 to 10 minutes, and sometimes more), be sure to charge the phone to 70-80% of the total battery capacity so that the update procedure is not interrupted due to problems with the phone’s battery.

Automatic Android update

The most affordable and least complicated way to update. Go to the options menu and select the “Phone Information” section. Here we go to the “Software Update” item. On your device, this section may be located somewhere else, so you may have to go through the settings.

Now tap on the “Update” button, having previously set the option to download updates only via Wi-Fi, so that the update does not “eat up” all your money from your account.

Option in the settings menu to automatically update the OS

When all the data from the manufacturer’s server has been downloaded, in the menu that appears, tap the “Install” button and wait until the device reboots.

Since in the manner described above you can only update your mobile device to a minor release build, you should also use a special utility from the manufacturer (for Samsung gadgets it’s Kies, for LG it’s PC Suite, etc.) or update “over the air” (most of companies that produce smartphones or tablets have such a proprietary feature).

Latest Android update, if it is already available on the server, you can download it to your device at any time using just such a program.

Manually updating Android firmware

Almost all service centers use this method, but we can easily update ourselves, using exclusively available means. The Odin system application is used for updating. You can download it on many web resources (for example, on the same w3bsit3-dns.com). Using this technique, you can only install a new version of the official firmware, but not a custom one.

1. download the Odin program. We need version 1.83 (or later) - it is very popular among technicians and is suitable for the vast majority of products

2. find and download an archive on the Internet with the firmware we need. After extracting the contents from the archive (you will need it first), you should have 3 files on hand: PIT, PDA and CSC

3. connect the smartphone to the PC. It is critical that the phone is detected correctly in Windows

4. launch Odin. If the device connection was successful, the port name in the program will light up in yellow in the corresponding field

Indication of successful connection of the device to the PC for updating in Odin

5. turn off the mobile device and switch it to Download Mode by pressing the home, power and volume down keys at the same time

6. Confirm activation of Download Mode by holding down the “Volume Up” key

7. in the central Odin window, select the downloaded files so that they correspond to the PIT, PDA and CSC objects

8. In Odin, click the Start button and wait until all files are updated.

If the Android system update went smoothly, a field with the inscription PASS in green will appear on the application screen.

Successful system update via Odin

Rollback to previous version

Perhaps you updated to one of the latest versions and were not satisfied (the phone is slow, errors appear frequently, you need to reboot, etc.). If necessary, you can roll back to any version you need. How to roll back?

1 way

Suitable for those who want to return the basic official factory firmware installed in the device at the time of its purchase in the store. This is quite easy to do. Go to the device settings and select the item responsible for resetting the settings (this can be “Privacy” or “Backup and reset”). On the test phone, this function was available in the “Backup and reset” menu in the “Personal data” category.

Section in the options menu designed to reset the device to its factory state

We go to this section of the menu and stop at the “Reset settings” item.
A form pops up warning you that all data from the gadget will be deleted. If the backups are already saved in a safe place, feel free to click “Reset phone settings”.
The phone begins to reboot. After 5-10 minutes it will boot again, with a clean base system on board.

Method 2 - reset to factory settings (hard reset)

turn off the phone/tablet
simultaneously press and hold down the “Volume Up”, “Home” (bottom center) and “Power” buttons. The Recovery menu opens.
Using the volume keys, select the “wipe data/factory reset” item.
press the power key to confirm your choice
in the next menu you need to confirm your decision. Select “Yes – Delete all user data” using the keys designed to adjust the volume
Press the power button again. The main menu appears in front of you again
Using the power key, select “reboot system now”

All is ready. Next time the factory version of the OS will boot.

How to rollback if a custom version of Android is installed (Cyanogenmod, MIUI, Paranoid Android)?

If you installed a custom ROM, you can return the official firmware in the same way as performing a manual update - using the Odin program already mentioned in the review. First, you will have to search the Internet for files with the firmware you need, individually suitable for your smart model. Perhaps the best resource for searching is the mobile portal 4PDA; here you can find any firmware for almost every phone model.

connect the mobile device to the PC
launch Odin
turn off the phone and enter it into Download Mode. To do this, press the home key, power key and volume down key.
when the phone is booted, press the volume up key to activate Download Mode
on the main Odin form, select the downloaded files as a match for PIT, PDA and CSC
in Odin, click the Start button and wait until all the files are updated.

The successful completion of the rollback procedure will be indicated by a green field with the inscription PASS at the top.

Answers to readers' questions

When will the new Android update be available?

Answer. Since a certain time passes between the immediate release of a new version of Android and the physical possibility of installing it on a gadget (from 2-3 to 6-8 months), you need to be patient and follow the announcements of companies.

Lenovo A1000, Android is not updated. I'm trying to update version 5.0 to the newest one. At first everything goes well, but then he writes “Error” and shows an opened Android with a red triangle with an exclamation mark hanging above it. What should I do? How to update the OS to the latest version?

Answer. Why isn't Android updated? The fact is that Android 5.0 is the latest OS version to which you can officially update the firmware on your phone. At least that's what users of the 4pda forum say. Of course, you can update your phone by installing custom firmware, but no one guarantees stability after such an update.

A year ago, the memory on my device died (the phone stopped turning on), it was replaced, but the firmware was not the original one (it’s no different, only the yellow Kernel inscription appears in the corner on the startup screen). Naturally, there are no updates for this firmware. Can I use Kies to roll back Android (install the native one) and update it?

Answer. In order to roll back the update, you need to reboot the phone in Recovery mode, select wipe data/factory reset, wipe cache partition and reinstall the firmware from the zip archive previously downloaded to the memory card. You can find the official firmware both on the manufacturer’s official website and on the 4pda forum, in the section with the corresponding name of your mobile device.

Acer Iconia A1-810 tablet. I don't have firmware updates... I click system update and it says "your device requires an update." How can I “force” it (forcefully update the Android system) or update it myself?

Answer. This tablet model was released about 5 years ago; it does not support new versions of Android, so the manufacturer does not provide firmware updates. You can look for custom (unofficial) firmware on the 4pda forum, but we do not recommend installing them - it is better to buy a new tablet than experiment with firmware at the expense of the stability and speed of the device.
